Question

(2n - 7n) * (8 + 6n) =

a. -14n^2 - 84n
b. 14n^2 + 84n
c. -14n^2 + 84n
d. 14n^2 - 84n

Answer 1

After simplifying (2n - 7n) to -5n, and then distributing -5n over (8 + 6n), we get -30n² - 40n, which doesn't match any of the provided answer choices. There might be an error in the question or options.

Step-by-step explanation:

To solve the expression (2n - 7n) * (8 + 6n), let's simplify it step-by-step. First, simplify the terms within the parentheses on the left side:

• 2n - 7n = -5n

Now, multiply this result with each term in the parentheses on the right side:

• -5n * 8 = -40n
• -5n * 6n = -30n²

Combine these two products to get the full expression:

• -30n² - 40n

Since none of the answer choices match this result, it seems there may be a mistake in the question or the answer options. Please review the original problem to ensure there's no error.
